- Abstract
- The purpose of this part of the paper is to present in preliminary form a mathematical theory for the energy and mass transfer in a pyrolyzing layer, to present a theory for the motion and heat-transfer characteristics of molten layers under the influence of wind stresses and body forces, and to show how the equations for these two layers can be coupled with the aerodynamic equations for a boundary layer with mass injection. A list is presented of the materials properties and physical measurements, which are required for the calculation of ablation rates. The various types of experiments which are sugested by a the theory for determining the necessary data are also discussed. In part I (General Behavior) of this paper, the role of pyrolysis, molten layers and mass transfer into the heat-source gas layer was discussed qualitatively.
